# The following two commands (inserted into the correct files) will let you 
# easily tell what commits are on your current branch that are not on the target branch.
# Usage:
#   git checkout master
#   git diff-branch origin/master # Shows all unpushed changes
#   git checkout my-new-feature
#   git diff-branch master        # Shows all commits on my-new-feature that are not on master

# In ~/.bashrc or ~/.profile
function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/\1/"
}

# In ~/.gitconfig
[alias]
    diff-branch = !bash -l -c "'git log $(git merge-base $(parse_git_branch) $0)..HEAD $@'"
